War! L Herrmann ATTOR Patented Sept. 10, 1935 I UNITED STATES PATENT OFFICE LUBRICATIN G MEAN 5' FOR ANTIFRICTION BEARINGS *6 Claims.

My invention relates to drive rod constructions such as used on locomotives and the like, and has v for its principal object to provide a suitable and eflicient lubricating meansv therefor.

5 A further object is to provide in a locomotive drive rod construction, means to provide a level of lubricant in the crank pin whereby the bearings may be properly supplied with lubricant therefrom.

10 Another object is to provide a lubricant carrying cartridge or cylinder'detachably mounted in the crank pin of a locomotive drive from which the lnbricant is distributed to the hearings on the crank pin.

15, A further object is to provide a crank pin having a bore in one end thereof in which is-mounted a cylinder formed of lubricant distributing material adapted to receive the lubricant'from a cartridge inserted therein and distribute the lu- 20 bricant to one or more bearings on the crank pin.

A further object is to provide a crank pin having a bore in the end thereof adapted to receive a cylinder formed of lubricant distributing mate-- rial, within which is mounted a cartridge formed 25 to distribute lubricant to the cylinder from whence the lubricant is directed through ports in the crank pin to the several bearings thereon.

Other objects, and objects relating toxietails of construction and methods of manufacture will 30 be apparentfrom the detailed descriptionto follow.

The invention, both as to the construction employed by way of illustration and its method of operation; together with the objects and ad- 35 vantages derived therefrom, will best be understood from the following description of a specific embodiment thereofwhen read in connection with the accompanying drawings in which 'like reference numerals refer to like parts 40 throughout the several views.

Fig. 1 is a diagrammatic perspective view of a locomotive drive truck in which my invention is incorporated.

Fig. 2 is an enlarged fragmentary detailed.secv in the bore of the crank pin surrounding the cartridge. r 55 I2 Fig. 1 I have diagrammatically illustrated a locomotive drive truck including a main drive rod 9, a driver axle I having a wheel II thereon, a front driver axle I2 with a wheel l3 thereon, and an intermediate driver axle I4 with a wheel Ii thereon. The wheels II, I3 and I5 are each pro' 5 vided with a crank pin l6 which are bored at I! to receive the lubricatingmeans presently to be described. The wheels II and I5 are connected by the rod I8 which fits over hearings on the crank pins I6 on the respective wheels and the wheels 10 I3 and I5 are connected by the rod I9 which also fits over bearings on the crank pins I6 on the respective wheels, the rod I9 being forked at both ends to straddle the rods 9 and 20. As each of the crank pins is .preferably provided with simil5 lar lubricating means, an illustration and descrip-. tion-of the detailed parts of one crank pin and its associated parts is thought to be suflicient.

As shown in Fig. 2, the crank pin I6 extending from the wheel I5 has a. journal face 2| over which is fitted a-bushing 22. The rod I8 has a flanged bushing 23 fittted therein and row of anti-friction rollers M is interposed between the bushings 22 and 23 to relieve the load on the bushings and provide a drive having the minimum 25 amount of friction. As previously stated, the

rod I9 is forked to straddle the driving rod 9 and it has a bushing 25 fitted therein which, as illustrated, is provided with flanges 26 atits opposite ends and a flange 21 formed centrally thereof to provide two race-ways for the rows of rollers 28 and 29 surrounding the bushings 30 forming the inner race member which is'iitted over the reduced end 3| bf the crank pin I6. Locking rings Iii and 33 are secured to the inner race member 35 30 to prevent longitudinal movement of the outer race member 25 and with it the rollers 28 and 29. L

The bore 11 in the rank pin I6 is formed to provide a shoulder 34 at its inner end, in which is 40 '35, the cartridge having a cylindrical wall or shell 39 screw-threaded at its inner end to receive the detachable end plate 4 I which is preferably beveled I at 42 to permit its easy insertion in to the reduced 48 are apertured at'58 and into which is inserted with lubricant.

end portion 43 of the bore I! in which it is supported. The outer end of the cartridge 38 is screwthreaded at 44 into the flanged lock nut 45 which is screw-threaded at 48 into the crank pin l6 so that both ends of the cartridge are firmly supported but it may be detached and removed 1 a wick 5|. Opposite the open end 49 of each lubricant conductor 48, the casing 39 is drilled at 52 so that the end 5| of the wick 5| extends therethrough, as'shown 'in Fig. 3, to wipe against the inner face of the ring 35. As illustrated, the wick 5| extends only half way around the aperture 58 or, in other words, in the position shown the upper half of the aperture 50 is left'open to receive the lubricant and conduct it to the wick, from which it is absorbed by the tube 35 and then delivered to the bearings. The outer end of the cartridge 38 is drilled to receive the'filler plug 55 which may be removed to refill the cartridge In assembling the oiling mechanism, the cartridge 38 is filled with lubricant to the level shown in Fig. 3 and is then inserted in the bore I! with the inner end of the cartridge seating in the reduced portion 43 thereof, the outer end thereof being screw-threaded into the flange nut 45. During rotation of the cartridge-with the crank pin oilwill be carried into theapertures 50 in the oil conductors 48 to lubricate the wick 5| so that as the exposed end 5| thereof contacts with the oil absorbing ring '35 that lubricant will be car-- ried thereto-from whence the oil is conducted through the several oil passages 58 to the bushing or inner race members '22 and 30 which are also provided with oil passages 51 so that lubricant will be carried to the rollers 24, 28 and 29 to thus lubricate thebearings for the rods connecting the wheels as shown.

, As lubricant is used from the cartridge 38 the filler plug 55 may be removed and the cartridge can be refilled or when it is'desired to clean the ring 35, the cartridge may be removed so that the ring ,35 may also be removed from the bore I'I in the crank pin l6 making it easy to maintain a fresh supply of clean lubricant at all times for the bearing and also so change the lubricant quickly with the minimum expense.

While I have shown one embodiment 01. my invention, it is tobe understood that changes in details of construction and methods of operation 'can be resorted to without departing from the spirit and substance of my invention. the scope of which is to be measured entirely by thescope of the sub-joined claims.
